    Sport Performance Sound. Mustang owners love the power and performance their GT's possess, especially when dropping it into a lower gear to pass slow moving traffic, but they find the sound of the stock exhaust a little anemic. So give your GT the exhaust note it deserves by upgrading to a Corsa Performance Sport Catack Exhaust System. Acoustically engineered and tuned, this Corsa Sport Cat-Back will give your V8 coyote powered Mustang a robust, sport performance sound under acceleration and a distinct rumble at idle, all without any annoying drone while cruising. As an added bonus a Corsa Sport Cat-Back will also improve your Mustang's exhaust flow for an increase of 5 RWHP and 4 RWTQ.

    Race Car Growl. Corsa Performance Sport Cat-Back Systems feature a very unique double helix X-Pipe that replaces the factory resonator Mid Pipe. The double helix "X" crossover design not only helps improve exhaust flow for an increase in power, but it also adds a crisp raspy, race car growl to the sound of your Mustang's exhaust.

    RSC™ Technology. Corsa Performance engineers all their mufflers using their very own patented Reflective Sound Cancellation® Technology (RSC™). RSC™ Technology is designed to give your Mustang's exhaust an aggressive sound under acceleration and a drone-free experience while cruising.

    Quality Construction. Corsa Performance proudly manufactures their Cat-Back Exhaust systems right here in the good ole USA. This Corsa Cat-Back is mandrel-bent from 3" diameter, premium grade, 304 stainless steel tubing for excellent exhaust flow and enduring corrosion resistance. The system includes a double helix X-Pipe and two high flow, straight-through sport mufflers. The mufflers feature a pair of mirror polished twin 4" Pro-Series tips. Step down flanges are included, so that this 3" Corsa Axle-Back can be installed with the factory 2.5" exhaust.

    Application. This Corsa Sport Cat-Back Exhaust System with Polished Quad Tips is designed to fit 2015-2017 Fastback GT Mustangs equipped with the factory Premium Chassis Package (Trim Levels: 400A/401A) and the 2018 Fastback GT Mustangs that is not equipped with the Active Valve Exhaust System.

    Application Note. The 2015-2017 Model Years will require the use of the Roush Rear Valance 421894 or 421919 for proper installation (valance sold separately). Does not fit convertible models.

      Corsa Sport cat-back

      Most companies claim direct fit bolt on. Had to do some modification to the rear hangers to make them hang evenly. Decent sound but wanted something more aggressive and should have went with the Corsa Xtreme.
